/* LanguageCoach site.
   The navy is sampled from the App Store screenshots themselves (#103C80 at
   the top of those frames), so the store images sit on the page without a
   visible seam. Cream text and the cream button are the app's own colours
   inverted onto it. System fonts only, one stylesheet, no JavaScript. */
